Figure 6 is an enlarged sectional view showing and the disposition of atray or pan supported in one of the grooves or recesses of the side wallmembers; and

Figure '7 is an enlarged sectional view showing in detail the assemblyand disposition of a side wall member and vertical frame member.

The present description will be made in reference to the use of thecabinet as a storage and shipping cabinet for baked goods carried on aplurality of trays or pans, although it is to be understood that mycabinet is adapted for other and analogous purposes. In referring to atray, it is to be understood that this includes pans or other devicesused for supporting or holding articles. In the preferred form of myinvention, all of the enclosing walls are made of sheet metal. Thismetal may be steel or other suitable metal, and for reducing the weightI prefer to use sheet aluminum or other lightweight metal. The metalused is suitable for forming into the required shape and for beingjoined by welding as herein described. a

The preferred form of my cabinet is comprised of two verticallypositioned, spaced and parallel side wall members I I, a top wall memberI2, a rear wall member l3, a bottom wall member I4 and an enclosing doorll. These members together provide an enclosed compartment providing asanitary and safe enclosure for shipping and storage of baked goods andthe like. The b'ottc'm wall member I4 provides the base of the cabinet,the bottom wall member It being formed-of a horizontally disposed pieceof sheet metal having downwardly extending flanges H-b around-itsperiphery. Adjacent the peripheral edges of wall member It there is aportion I 4--a running a,sos,soo

3 aroundthebasememberandformingaledgeextending a short distance out fromthe side walls, rear walls and door of the cabinet. This peripheral edgeportion Il-a and flange I4b provides a bumper on the four sides of thecabinet to protect the walls of the cabinet against being dented,scraped or injured during shipment or otherwise as might occur from thecabinet being moved against the wall or against another cabinet.

Carried by, and extending vertically upward from the bottom wall memberI4 on the two sides of the cabinet, are two side wall members II. Theside wall members II are vertically positioned, spaced apart anddisposed parallel to each other. The side wall members II of metal areformed to be recurrently bent back upon themselves at right angle bends,or they may be saidtobecorrugatedinabroadsenseofthe word. As so formedeach side wall member II has formed therein a plurality of grooves,channels or longitudinal "-11. These grooves II-a are disposed in ahorizontal plane, paralleltoeach otherandspacedapartinrespeet to each ofthe wall members. The open inwardly of the cabinet, and oppositerecesses II-a of the two wall members face each other to provide pairsof grooves or channels in horizontal planes adapted toaccommodatethetray orpan,suchaspan2l. Aseach pair of opposite groovesII-a accommodates a pan 2|, as many pans 2| as there are opposite pairsof grooves provided in the side wall members may be accommodated in thecabinet.

There is an outer wall II-b opposite each internal recess or groove"-11. The recurrently occurring outer wall surfaces "-12 are disposed inone vertical plane as shown ,in the drawing. There is a connectingportion lI-c extending between each of the recesses or grooves II-a.This connecting portion II-c is disposed in another vertical planeparallel to the vertical plane passing through outer wall IIb.Preferably, the connecting portions Il-c are of greater longitudinaldimension than the wall "-11 forming the back of each recess "-4. Eachrecess or groove Il-a has a bottom wall II-d forming a supporting ledgefor the support of trays or pans iI. Also, each recess or groove II-ahas a top wall II-e. The connecting portion II-c extends verticallybetween top wall lI-e of each recess "-4 to the bottom wall iI-d of thenext recess above it. The bottom ledge or wall lI-d is somewhatchamfered at the junction with connecting portion II-c as indicated atII] in Figure 6 of the drawing. The wall of the recess is chamfered atI|-! for the purpose of better accommodating the type of tray or pan 2|illustrated in the drawing and often used in the bakery business foraccommodating baked goods. The pan or tray II has a rim II-o at itsperipheral edges and which rests upon the ledge "-41. ThepanortraylIalsohasa sunken or depressed bottom 2I-b, the walls of the tray or pansloping down at an angle from the rim II-a to the bottom 2Ib. Thechamfered edge II-j better accommodates pans or trays of thisconstruction. Each pan or tray II is adapted to be slid into the cabinetwith opposite rims II-a positioned in the opposite recesses or grooves"-0. A plurality of trays or pans II may be accommodated in the cabinet,each pan or tray-being positioned in one of the pair of recesses "-41.Thus a plurality of trays arranged in a vertical row may be supportedone above another in the cabinet, and each tray may 'the top surface ofbottom wall member I. The

abutting surfaces of bottom wall I4 and side wall members II are weldedtogether, preferably by resistance welding so that the side wall membersII are flrmly secured to the bottom wall member I4 and the iuncturesalong the meeting surfaces are substantially sealed or closed.

The rear wall member It, also preferably made of sheet metal, isdisposed in a vertical plane and extends between the vertical rear edgesof the side wall members II to close the rear of the cabinet. Reinforcedcorner portions are provided at the rear corners of the cabinet bybending or folding the vertical opposite edges of rear wall member II ina manner disclosed in Figures 4 and 5. The sheet metal of the rear wallmember I3 is folded back upon itself to form a folded portion It-c. Thefirst folded portion is again bent at right angles to the rear wall ofthe cabinet to form a flange I 3-4 reinforced with the folded portionII-b shown in detail in Figure 5. Thus at each vertical edge of rearwall member I3, there is provided a reinforced corner portion or flangeextending at right angles to the rear wall of the cabinet. The flange ofrear wall member it composed of portions Il-a and Il-b, is disposed nextadjacent to wall Il-b of the two side wall members II. Inasmuch as wall"-4) and wall I I-c of each side wall member are in two spaced andparallel vertical planes, the flanged portion of rear wall member It canbe disposed next adjacent to only one of these walls, as the flangedportion composed of II-a and II-b is straight in a vertical direction.The flanged edge portions of rear wall Il-a. are joined to the severalwall portions IIb of the respective wall members II, preferably beingjoined by resistance welding at a location indicated by referencecharacter 22 in Figure 5. The welding of flanges I3-a of rear wallmember I3 to side wall members II is done at recurring intervals alongthe length of the side wall members, these intervals being determined bythe irregular configuration or corrugation of the side wall members. Itis preferable to have all of the channel walls "-1) welded to theadjacent flanges of the rear wall member so that every one of the wallportions "-1) are welded or otherwise suitably joined to the flangedcorner portion. However, in practice a relatively few of the wallportions I I-b may be skipped in the welding operation so thatsubstantially'all of the wall portions "-12 are welded or otherwisesuitably joined to the flanged corner portions of rear wall members It.

At the front vertical edges of side wall members II, there are twovertical frame members It and II extending the height of the cabinet andlongitudinally of the side wall members. These frame members I5 and Itare made of metal and may be made in a suitable structural form forstrength and rigidity, such as the channel members I5 and I6 illustratedin the drawing. The respective frame members are positioned at oradjacent the front edge portions of side wall members II and aredisposed next adjacent the wall portions IIb of the res tive side wallmembers. The webs of the respective frame members I5 and It are welded,preferably by resistance welding, to the wall portions "-41 of the sidewall members. The resistance welding is preferably done at interengagedsurfaces, such 8 as locations indicated by the reference character 23 inFigure 7. Preferably all of the wall portions ll---b of each side wallmember are welded or otherwise suitably joined to the adjacent vertijcal frame member. However, in practice a few of 'thewall portions lI-bof each side wall member may be skipped so that substantially all of thewall portions ll- -b are welded or otherwise suitably joined to therespective frame members.

The top wall member I2 is a horizontally disposed and rectangular pieceof sheet metal formed with downwardly extending flanges l2a at its fourperipheral edges. Two of the flanges l2--a overlap and are disposedadjacent the side wall members H and provide a closing of the cabinet atthe juncture of top wall member 12 and side wall members ll. Preferablythe opposite flanges I2a adjacent the side wall members II are welded orotherwise suitably joined to the upper edge portions of side wallmembers ll, preference being given to resistance welding of adjacentsurfaces. The flange l2-a at the rear of the cabinet overlaps the rearwall member I3 and is also preferably joined thereto by resistancewelding. The top wall member l2 acts to enclose the top of the cabinetand also acts to tie together the three walls and to brace them in theirvertical position. The front flange l2-a of top wall member l2 extendsbetween the side wall-members II at the front of the cabinet and aids toprovide a brace and strengthening element for rigidity of the cabinet atthe front thereof. The front flange I2--a extends down at the front faceof the cabinet only a short distance and does not obstruct the front ofthe cabinet for the ready insertion and withdrawal of trays in andout'of the pairs of grooves or recesses.

The door I! is adapted to close the front of the cabinet so that theinterior is entirely closed. The door I1 is preferably made of sheetmetal formed to have a front wall and an inner wall ll-a, thereby givingstrength and rigidit to the door and also providing the protection of adouble-walled door. Three hinges 20 suitably spaced apart are carried bythe vertical frame member IS, the fixed portion of each hinge beingsecured by welding or other suitable means to the flange of frame memberHi. The hanging of doors I! on the cabinet is such that the door may beswung on its hinges to open the cabinet or swung to a closed position toclose the front of the cabinet. A suitable latch or catch mechanism iscarried by the vertical frame member l5, and this mechanism is adaptedto secure the door I! in closed position. A suitable closing mechanismis provided by a hinged bracket 24 carried by the frame member IS. Thehinged bracket 24 may be secured to the frame member 15 by welding orother suitable means. The hinged bracket 24 carries with it two latchesor catches 25 spaced apart and interconnected by a handle 26. Thearrangement is such that the latches 25 may be moved out of the path ofthe door by swinging the handle 26 upwardly on the hinged bracket 24,and such that the latches 25 may be swung down in front of the free edgeof the door to lock or secure the door in closed position. The framemember l5 provides a suitable anchor for securing the locking mechanism,and provides a firm abutment for the vertical edge of the door adjacentthereto. The frame member l6 provides a suitable anchor for the hinges20 and a firm abutment for the vertical edge of the door adjacentthereto.

It isto be noted that the form of side wall members II is such that alateral rigidity is provided to each side wall member. The angularlydisposed sides defining each recess or groove prevents or limits bendingor distortion of the side wall members laterally of each side wallmember. They thus provide framing or bracing elements for the side wallmembers embodied within the sheet metal of the side wall membersthemselves. Also the corner flanged portions i3a. welded to the severalwall portions l|b along the length of the side wall members, providerigidity longitudinally of the respective side wall members. Thereinforced corner portions welding the rear wall member to the side wallmembers, provide strength and rigidity to the side wall members and rearwall member throughout the height of the cabinet. The frame members I5and I6 provide rigidity to the side wall members at the front verticaledge portions thereof to provide rigidity to the side wall memberslongitudinally thereof in the vicinity of the front of the cabinet. Thewall portions ll--b welded at intervals along the length of the framemembers, provide a bracing or framing action for the cabinet. It istherefore seen that by the construction of the side wall members, sheetmetal forming the side wall members forms the dual purpose of providinggrooves or channels for receiving the trays and also for providingtransverse frame elements for the side wall members. 1

The entire assembly, construction and fabrication of the cabinet is suchthat the use of an external or auxiliary frame for providing strengthand rigidity to the wall is largely eliminated. Only a minimum ofmaterial is required for the amount of strength, rigidity and enclosurerequired for a cabinet to meet desired service specifications. Mycabinet is strong, durable and economical in construction, and at thesame time provides a large degree of universal use in service. The framemembers l5 and I6, besides providing strength and rigidity at the openfront end of the cabinet, also provide mounting means for the door and areinforcement of the side wall members where the trays are firstinserted into the cabinet and where distortion or spreading apart of theside walls is most likely to occur.

To provide for ready transport and moving of the cabinet, suitablecasters may be mounted to the bottom of the cabinet. Four casterbrackets it are secured by welding or other suitable means to the bottomof the bottom wall I4 in such a manner as to permit swiveling of thecasters. Caster wheels I9 rotatably mounted on the brackets, provide forthe rolling of the cabinet across a floor or other surface. The castersare of the swiveling type so that the cabinet may be readily moved in aplurality of directions.

While in the preferred form of my invention it is desired thatresistance welding may be utilized for ease of fabrication, it is alsoto be understood that spot welding or other suitable joining of theadjacent metallic wall portions may be utilized. In some instances, itmay be desired to connect the parts together by other means other thanby welding, such as, for example, securing the caster bracl rets l8 tothe bottom wall H by nuts and bolts. However, for efficiency infabrication and for obtaining the best results in a neat, strong andwell-inclosed cabinet, I prefer to use welding as a means for joiningthe parts together.

The description contained in the appended aeoasoo claims is included inthe present disclosure and made a part of this description by referencethereto.

Although the invention has been described in its preferred form with acertain degree of particularity, it is understood that the presentdisclosure of the preferred form has been made only by way of exampleand that numerous changes in the details of construction and thecombination and arrangement of parts may be resorted to withoutdeparting from the spirit and the scope of the invention as hereinafterclaimed.
